  1. We did this activity with our sixth grade classroom, and it worked great! It helps to show the kids the dirty water before they start building to give them an idea of what their filters will need to clean out of the water. 

  2. We did it with a classroom of 5th grade ESL students, and it was semi-successful. We didn't use the NXT light sensor; we just had cups of before and after water, so any measure of success we had was just by the students looking at the water. They also seemed somewhat bored during the assembly of the filters, and a few students lost focus. They were surprised and impressed at how well the water was cleaned (more than we as STOMPers were - test the filter once before the class to know what to expect), but clean-up was quite messy...
